Related Art

In 5G systems, Enhance Mobile Broadband (eMBB) and Ultra Reliable andLow Latency Communication (URLLC) are two typical service types. A newModulation and Coding Scheme (MCS) table has been defined forrequirements of lower target BLER (10{circumflex over ( )}−5) of URLLCservices in the 3rd Generation Partner Project (3GPP) New Radio (NR)Release 15.

In order to support URLLC services of higher requirements, for example,higher reliability (eg. target BLER is 10{circumflex over ( )}−6), lowerlatency (eg. 0.5-1 ms), etc., the 3GPP Radio Access Network (RAN) #80session had approved a Study Item (SI) of URLLC enhancement of NRRelease 16, in which enhancements to Hybrid Automatic Repeat reQuest(HARQ) feedback/Channel State Information (CSI) feedback are a key pointto be studied.

SUMMARY

In view of the above problems, the disclosure provides a solution. Itshould be noted that the embodiments of the disclosure and thecharacteristics in the embodiments may be mutually combined arbitrarilyif no conflict is incurred.

transmitting K radio signals and the first bit block in K time-frequencyresource groups.

Herein, time-domain resources occupied by the first time-frequencyresource group are overlapping with time-domain resources occupied by atleast one of the K time-frequency resource groups, and any two of the Ktime-frequency resource groups are orthogonal in time domain; the Kradio signals are transmitted in the K time-frequency resource groupsrespectively, and the first bit block is transmitted in only K1time-frequency resource group(s) among the K time-frequency resourcegroups; the first signaling corresponds to a first type or a secondtype, and whether the first signaling corresponds to the first type orthe second type is used for determining the K1 time-frequency resourcegroup(s) from the K time-frequency resource groups; the K is a positiveinteger greater than 1, and the K1 is a positive integer not greaterthan the K.

In one embodiment, the problem to be solved by the disclosure is: how toenhance the transmission of a UCI when a PUCCH is not orthogonal to aPUSCH in time domain, in view of the requirements of higher reliabilityin NR Release 16.

In one embodiment, the problem to be solved by the disclosure is that:in current standards, when a PUCCH reserved to transmit a UCI is notorthogonal to one PUSCH in time domain, the transmission of the UCI ischanged onto the PUSCH. In NR Release 16, one PUSCH probably occupiesfew time-domain resources, for example, one or several multicarriersymbols, there might be multiple PUSCHs transmitted in one same timeslotof one same carrier or in one same subframe, and the multiple PUSCHs maybe multiple repeated transmissions of one Transport Block (TB) or may betransmissions of multiple different TBs; when a UCI is not orthogonal toat least one of the multiple PUSCHs, on which of the PUSCHs the UCI isto be transmitted is a key problem to be reconsidered.

In one embodiment, the problem to be solved by the disclosure is that:in current standards, when a PUCCH reserved to transmit a UCI is notorthogonal to one PUSCH in time domain, the transmission of the UCI ischanged onto the PUSCH. In NR Release 16, one URLLC PUSCH probablyoccupies few time-domain resources, for example, one or severalmulticarrier symbols, there might be multiple URLLC PUSCHs transmittedin one same timeslot of one same carrier or in one same subframe, andthe multiple URLLC PUSCHs may be multiple repeated transmissions of oneTB or may be transmissions of multiple different TBs; since an eMBB UCIand a URLLC UCI have different requirements on transmission latency,when a UCI is not orthogonal to at least one of the multiple URLLCPUSCHs, a service type corresponding to the UCI needs to be consideredwhen determining on which of the PUSCHs the UCI is to be transmitted.

In one embodiment, the essence of the above method is that: the firsttime-frequency resource group is a PUCCH, the K time-frequency resourcegroups are K PUSCHs, the first bit block is a UCI, the PUCCH is notorthogonal to at least one of the K PUSCHs, the first type correspondsto URLLC services, and the second type corresponds to eMBB services. Theabove method has the following benefits: on which of the PUSCHs the UCIis to be transmitted is determined according to the service typecorresponding to the UCI.

According to one aspect of the disclosure, the above method ischaracterized in that: when the first signaling corresponds to the firsttype, the K1 time-frequency resource group(s) is(are) K1 earliesttime-frequency resource group(s) in time domain among K2 time-frequencyresource group(s) respectively; each of the K2 time-frequency resourcegroup(s) is one of the K time-frequency resource groups, and the K2 is apositive integer not less than the K1 but not greater than the K; the K2is equal to the K and the K2 time-frequency resource groups are the Ktime-frequency resource groups respectively; or, the K2 time-frequencyresource group(s) is(are) all time-frequency resource groups overlappingwith the first time-frequency resource group in time domain among the Ktime-frequency resource groups.

In one embodiment, the essence of the above method is that: K2time-frequency resource group(s) is(are) K2 PUSCH(s) among the K PUSCHs,and a URLL UCI is transmitted on K1 earliest PUSCH(s) in time domainamong the K2 PUSCH(s). The above method has the following benefits: thetransmission low latency of the URLLC UCI is guaranteed.

According to one aspect of the disclosure, the above method ischaracterized in that: when the first signaling corresponds to thesecond type, the K1 time-frequency resource group(s) is(are) K1 latesttime-frequency resource group(s) in time domain among K3 time-frequencyresource group(s) respectively; each of the K3 time-frequency resourcegroup(s) is one of the K time-frequency resource groups, and the K3 is apositive integer not less than the K1 but not greater than the K; the K3is equal to the K and the K3 time-frequency resource groups are the Ktime-frequency resource groups respectively; or, the K3 time-frequencyresource group(s) is(are) all time-frequency resource groups overlappingwith the first time-frequency resource group in time domain among the Ktime-frequency resource groups.

In one embodiment, the essence of the above method is that: the Ktime-frequency resource groups are K URLLC PUSCHs respectively; in orderto guarantee the transmission high reliability of the URLLC PUSCH, the KURLLC PUSCHs are repeated transmissions of one same TB respectively, theK3 time-frequency resource group(s) is(are) K3 PUSCH(s) among the KURLLC PUSCHs, and an eMBB UCI is transmitted on K1 latest PUSCH(s) intime domain among the K3 PUSCH(s). The above method has the followingbenefits: when K3 is greater than K1, the eMBB UCI does not affect thetransmission of the (K3-K1) earliest PUSCH(s) among the K3 PUSCH(s), anda receiving terminal may parse the TB relatively early based on multiplerepeated transmissions; therefore, this method is beneficial to thetransmission low latency of the URLLC PUSCH.

The method according to claim 16, wherein when the firstsignaling corresponds to the second type, the K1 time-frequency resourcegroup(s) is(are) K1 latest time-frequency resource group(s) in timedomain among K3 time-frequency resource group(s) respectively; each ofthe K3 time-frequency resource group(s) is one of the K time-frequencyresource groups, and the K3 is a positive integer not less than the K1but not greater than the K; the K3 is equal to the K and the K3time-frequency resource groups are the K time-frequency resource groupsrespectively; or, the K3 time-frequency resource group(s) is(are) alltime-frequency resource groups overlapping with the first time-frequencyresource group in time domain among the K time-frequency resourcegroups.
 19. The method according to claim 16, wherein the K1 ispredefined, or the K1 is configurable, or a number of bits comprised inthe first bit block is used for determining the K1; or, the methodcomprises: transmitting a first radio signal, wherein the first bitblock is related to the first radio signal.
 20. The method according toclaim 16, comprising: transmitting a first radio signal; wherein thefirst bit block is related to the first radio signal; the first bitblock is used for indicating whether the first radio signal is correctlyreceived; when the first signaling corresponds to the first type, thefirst signaling is used for indicating a MCS employed by the first radiosignal from a first MCS set; when the first signaling corresponds to thesecond type, the first signaling is used for indicating an MCS employedby the first radio signal from a second MCS set; and a target BLER ofthe first MCS set is less than a target BLER of the second MCS set.
